CUFF BUTTON.

Application led February 1G, 1925.

To all zo/0m t may concern:

Be it known that I, GERHARD VVULLUM, a citizen of the United. States,and a resident of Chicago, county of Cook, and State of lllinois, haveinvented a new and useful Improvement in Cuff Buttons, of which thefollowing is a full, clear, and exact description.

My invention relates to improvements in cuff buttons and particularlythat type having two cooperating parts which are intended for separationand engagement with one another at will, and it consists in thecombinations, constructions, and arrangements herein described andclaimed.

An object of my invention is to provide a cufll button of the characterdescribed in which the cooperating' parts when pressed together becomeengaged, and which must be pressed together to release the parts. Theparts may not be disengaged by pulling them apart as in the ordinaryconstruction.

A further object of my invention is to provide a cuff button of thecharacter described in which the flexible or moving parts are entirelyencased.

A further object of my invention is to provide a cull button of thecharacter described in which particularly novel means is employed forcausing the cooperating members to become released from one another whenpressed toward each other.

A further object of my invention is to provide a cuff button of thecharacter described which is simple in construction, durable andthoroughly practical for the purpose intended.

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointed outin the appended claims.

My invention is illustrated in the aecompanying drawings, forming partof this application, in which- Figure l is an enlarged view of myimproved cuff button, a part thereof in sec-` tion,

Figure 2 is a view of the device shown in Figure l with the co-operatingparts engaged, and

Figure 3 is a view of the device shown 1n Figure l with the parts inposition for disengagement.

In carrying out my invention I malte use of two cooperating parts A andB. These Serial No. 9,586.

parts have the outward appearance of the ordinary separable cuff button,the part A being constructed to be received in the button hole at oneside of the cuff of a shirt, and the part B being constructed to bereceived in a button hole in the opposite side of a cuff. My inventionconsists in novel mechanism for engaging and permitting thedisengagement of the parts A and B with one another.

The part A Jis provided with a substantially conical tongue portion lhaving a shoulder 2 extending entirely around the tongue intermediateits length, thus separating the tongue into a body portion and a headportion 8 whereby the tongue l is substantially rigid in constructionand securely fixed in any suitable manner to the part A.

The part B is constructed, as reference to Figure l will show, of sheetmetal and ha. the same outward contour of the part A. This structureprovides a hollow portion t on the interior of the member B which isenlarged at by the provision of a radially extending iiange portion 6formed on the body portion of the part B. This construetion is alsofound in part A.

A resilient metal sleeve 7 is partially received within the hollowportion 4c and is constructed with a radially extending vflange 8adjacent to its upper end 9. The flange 8 is adapted to extend withinthe enlarged portion 5 of the hollow portion iand therefore serves tolimit longitudinal movement of the sleeve 7.

The sleeve 7 has a pair of diametrically opposed inwardly extendingtooth members Owhich are adapted to engage with the shoulder 2 of thetongue l when the tongue is projected within the sleeve 7, and tosecurely hold the tongue against unintentional withdrawal from thesleeve.

Means for disengaging the teeth l() from the shoulder 2 of the tongue isprojected in a resilient metal knob ll secured at 12 to the innermostend wall of the hollow portion 4.

From an inspection of the part B in Figure l it will be noted that thesleeve 7 has several longitudinally extending slits 13 therein, therebypermitting the spreading of adjacent portions of the sleeve outwardly attheir lowermost end when the sleeve 7 is forced downwardly upon the knob1l (scc Figure 3).

icoA

rihe liexible knob ll has slits let therein so that it may be separatedas by engagement of the tongue portion il therewith (see Figure but sothat it may not be constructed as by engagement of the lowermost end l5of the sleeve 7. It is therefore apparent that the tongue l may beforced downwardly until the sleeve 7, which must move therewith byvirtue of engagement of the end 9 with the flange (i, has spreadsutiicientiy at its lowermost end i5 to cause the teeth i() to disengagefrom the shoulder 2 of the tongue so that the parts A. and B may beseparated.

From the foregoing description of the various parts of the device theoperation thereof may be readily understood. The parts A, and li areinserted in the cull' of the shirt sleeve in precisely the same manneras the ordinary type of separable cuit' link, whereupon the tongue .l isprojected into the sleeve 'i' of the part B sufiiciently far 'to permit'the teeth l0 to engage with the shoulder 2 thereof. The resilientproperty of the sleeve permits the head portion 23 of the tongue to bepassed beyond the work engaging portion of the teeth l of the sleeveeasily, so that the engaging of the cooperating parts ri and B may beaccomplished with little ei'l'ort.

tiny attempt to move the partsl )i and li apart from one another at thistime will be unsuccessful due to the fact that the teeth l() securelylock the tongue l from withdrawal from the sleeve.

ln order to separate the parts A and il as in opening the shirt cuff,the wearer will force the parts A and B toward one another as shown inFigure 3, thus causing the flange 6 to engage with the end 9 of thesleeve 7 and the sleeve will move inwardly of the hollow body portion fiin such a manner as to lcause its lower end l to spread by engagementwith the knob il, This causes the teeth i() to assume the position shownin iigure and permits the disengagement of the tongue il therefrom.rlhus the tongue is releaed from ei'igagement with the teeth and theparts A. and B may be separated with ease.

While l have shown a cuil' button, it will be understood that theconstruction might be applied to buttons for other uses, such as forbuttoning curtains or the like.

l claim:

l. A enti' button of the character described comprising al pair ofcooperating parts each adapted to be secured to the cull of the garmentor the like, a tongue carried by one of said part-s extendinglongitudinally therefrom on the axis of said part, a sleeve slidablydisposed partially within the other of said parts and concentric withthe axis thereof, said sleeve being expandable at its innermost end andhaving teeth project ing inwardly therefrom for engagement with saidtongue on said first named part when said tongue is projected within thesaid sleeve, and means associated with each of said parts for spreadingsaid sleeve thereby moving said teeth out of engagement with said tonguewhen said first and second named part-s are forced toward one another.

2. A cuff button of the character described comprising a. pair ofcooperating parts each constructed for engagement with the cuff of agarment, and means associated with said parts for engaging said partsone with the other, whereby said parts may not be pulled apart, andwhereby said parts are :tree from engagement with one another whenpressed toward one another, said means including a tongue carried by oneof said parts, and a toothed sleeve carried by the other of said parts,said toothed sleeve being slidably disposed on its associate part andhaving a portion thereof projecting therefrom and extending 'toward thecomplementary part whereby movement of said sleeve inwardly of itsassociate part will disengage the tongue.

3. A cuff button of the character described comprising a pair ofcooperating parts each constructed for engagement with the cuff of agarment, means associated with said parts for engaging said parts onewith the other, whereby said parts may not be pulled apart, and wherebysaid parts are free from engagement with one another when pressed towardone another, said means including a tongue carried by one of said parts,and a. toothed sleeve (,-arried by the other of said parts, said toothedsleewuVx being slidably disposed on its associate pari, and having aportion thereof pro jeeting 'therefrom and extending toward thecomplementary part, whereby movement of said sleeve inwardly of itsassociate part will disengage the tongue, and other means disposedwithin said last named part for yiel lingly opposing the movement ofsaid tongue inwardly of the sleeve.
